Question

Sarah earns a 5% commission for each house she sales. Write an equation that relates Sarah's total incomes (T), if she has a base salary of $25,000 plus 5% of her sales (x)

Answer 1

`T = 25000 + 0.05x`

Explanation:

Given

`Salary = 25000`

`Commission = 5\%`

Required

Write an equation when sales = x

The equation can be written as:

`Total (T) = Salary + Commission * Sales`

This gives

`T = 25000 + 5\% * x`

Convert percentage to decimal

`T = 25000 + 0.05 * x`

`T = 25000 + 0.05x`
